RESISTING SAFETY LANDER FOB AERIAL MACHINES.

Application filed September 3, 1925. serial No. 54,288.

To all 'ulzom. it may concern I Be it known that I l-lasnuotjcu .LWVIL- Lruis, a citizen of the l'nited States, residing. at Brevard, in the county of Transyhvania andState of Yortli Carolina,have invented certain new and useful Improvements in a Resisting Safety Lander for Aerial Machines, of which the following is a specification.

The present. "for prov ding invention relates to a device a safety landing of aerial inaif chines generally, and particularly aeroplanes. The device is in the general form of a folded parachute carried on one of the planes of the aeroplane so as not to interfere with the proper normal function thereof. ,The device has incorporated therein means. whereby the parachute like' structure may be brought into active operation,

and function as the ordinary parachute, so.

that the aeroplane mayfall slowly to the ground,

A very important object of the invention is to provide a device of this nature having an exceedingly simplc' construction, one which is thoroughly reliable and etlicient in use and operation, one which is strong, du-

' ra-ble, inexpensive to manufacture, not likely to easily become out of order, easy to manipulate, and otherwise well adapted to the urpose for which it is designed.

lVith the aboveand numerous other objects in View as will appear as the description proceeds, the invention resides in cerr' tain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing Figure 1 is a top plan view of an aeroplane with'my iproved structure incorporated thereon.

Figure 2 part in a verti n view thereof, showing a longitudinal section therethrough,

Figure 3 IS a plan VlGW showing. the arcuate ribs of the device extended, and

Figure 1 is a fragmentary plan View showing the bows part-1y folded.-

Referring to the drawings in detail it will be seen that an ordinary aeroplane of the bi-plane type has been shown in the drawing, and any other suitable aerial vehicle may be substituted therefor. The aeroplane shown consists of a fuselage 5 having the upper plane 6, and the lower as shown in Figure 3.

plane 7 associated therewith in the usual manner. A bracket 8 is mounted in the bot- ,toin of'the fuselage, and has journaled therein a shaft 9 operable through crank 10. On this shaft within the bracket 8 there is fixed a. drum 11 having a cable 12 wound thereabout. at tubular casing 13 rises-from the bracket 8 and is braced by suitable guy wires 14 fixed to the bottom-of the fuselage asat 15; An inwardly projecting flange 16 is provided at the upper end-of the tubular casing 13. A rod 17 is slidable in the casing '13 and intermediate its ends is provided with a fixed collar 18. A coil spring 19 is disposed about, the rod between the bracket 8 and the collar 18 and normally'tdnds to extend-the rod which is held retracted-in the casing by the cable 12 wound about the flange 16 so that thespring 21 will function harebuffer elements 2t on the ends thereof.

In the present embodimentof the invention four arcuate ribs are attached to the head 22. Two of the arcuate ribs are indicated generally by the letters A, and the otheritwo of the arcuate ribs are indicated generally by the letters B. Each a-rcttate rib A includcsa fixed section 25 radiating from the head 22 at right angles to the arms 23, and terminates in an offset stop 26. A section 27 is engaged with the outer end of the section 25 bya ring hinge 28. The section 27 terminates in an offset stop 29. A section 28 1s engaged with the end of the section 27 by a ring hinge 30. A spring 31-is fixed to section 25, and a spring 31 is fixed to the section 27. The section 28 pulls over upon the section 27 as is shown in Figure 4, and the sections 28 and 27 when thus folded, fold upon the section 25. The springs 31 have a tendency to unfold'these arms so'that they will swing to an aligned extended position Each arcuate rib .B consistsof a section 32 which is connected to the head 22 by a ring hinge 33, a section 27 is hinged to section 32, and a section 28 description thereof is necessary. Springs 31 are associated with the sections of arcuate ribs B in the same manner that they are as sociated with the sections of the areuate rib A. Seet1on28' of each arcuate lll) B is adapted to fold upon section 2t, and

these sections 27 and 28 when folded upon in the folded positions indicated to advantage in dotted lines in Figure 1 by cables attached to the extremities of the endsections 28 and 28. These cables are trained through suitable eyelets 36 provided on the head 22 and extend down ahme'side the tubular casing 13 and may be held in any suitable manner in the fuselage 5 so that when they are released, the various springs 31 and 34 will be brought into play to extend the sections of the areuate ribs.

A cover 36 preferably constructed of oiled silk is attached to the end sections 28 and 28 in any suitable manner. Vhen the sections of the arcuate" ribs are folded, the cover is folded .on the upper plane 6 as is indicated to advantage in Figuresl and 2.

lVhen in this folded position, a shield 37". prevents the same from interfering with the proper functioning of the plane 6. This shield 37 is hingedly associated with the forward edge of the plane by spring hinges 38 so=that the same will be pushed out of the way when the arcuate ribs are extended as previously indicated. By pulling upon the cables 35 the arcuate ribs may be folded with the cover and the rod 17 may be tracted in the casing by winding the cable 12 on the drum 11.

It is thought that the construction, operlar casin ,ation, and advantages of the invention will now' be clearly understood without a. more detailed description thereof; The present embodiment of the invention has been disclosed merely by way of example, and in practice'attains the various features of advantage enumerated as desirable in the statement of the invention and the above description. It is apparent that numerous changes in the details of construction, in the sizes, in the materials, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described the invention, what I claim as new and desire to secureby Lets ters Patent is:

1. In combination, an aerial vehicle ill-- eluding a fuselage, and a plane, a tubular casing extending upwardly from the fuse laee through the plane, a rod slidable in the .tulmlarcasing, spring means normally holding said rod extended, buffer means associated with said rod, a head on the upper end of said rod, arcuate ribsextending from said head formed in foldable sections, means normally holding, said sections extended,

means for folding the sections, a cover associated with the sections.

2. In combination, an aerial vehicle including a fuselage, and a plane, a tubular casing extending upwardly from the fuselage through the plane, a rod sildable in the tubuspring means normally holding said rod extended, buffer means associated with said 1'od,a head on the upper end of said rod, arcuate ribs extendingfroin said head formed in foldable sections, means nor mally holding said sections extended, means for folding the sections, a cover associated, with, the sections, and a shield having a spring hinged connection with the forward edge of the plane for preventing the folded sections and cover from interfering with the proper operation thereof.

In testimony whereof I afiix my signature.
